' 2 Claims.

This invention relates to shingles for the roofs of buildings, and more particularly to shingles made of any `sort of composition material of any kind.v

It is the prime object of ythe invention to provide an improved interlocking shingle, so formed, cut and recessed, that a plurality of the` shingles may be laid upon a roof and interlocked in a new and 4improved manner, yielding certain advantages over other or similar shingles.

Another object is to provide a composition shingle Vgenerally rhomboidal in shape on a plan view for providing weather edges at bottom and angle or water shedding edges at one overlapping side, and providing also an Offset extension for facilitating the alignment as wellas the laying of superposed layers of shingles, the said single having peculiarly formed interlocks, or interlocking incisions in their lower or weather edges whereby superposed layers are efectually locked together as laid, in an air and water-tight formation.

In the drawing:

Figure 1 is a plan View of a single shingle, as formed in accordance with my invention.

Figure 2 is a plan view of an assembly of superposed shingles as laid on a roof, the individual shingles being on a reduced scale as compared to Figure l.

Figure 3 is a plan view of a shingle similar to that of'Figure 1 and on the same scale, the incisions however being omitted.

Figure 4 is a plan view similar to that of Figure 2, showing an assembly of shingles of the form of Figure 3, as laid upon a roof.

Shingles formed in accordance with my invention are shown at 5 and 5a, in Figures l and 3. These shingles are formed with rhomboidal body portions 6, 6a, and with shorter, laterally offset and corresponding rhomboidal extensions 1, 1a

designed to be positioned in under-lapped rela tion as to adjacent or laterally contiguous shingles of an assembly.

These shingles are formed of any desired or suitable material, such as the conventional coinposition material. The upper edges 8, 8a are designed to underlie superposed shingles in regular order and overlapped relation.

The lower edges IEI, Illa of these shingles extend parallel with the upper edges and extend laterally to the right hand, to include the offset extensions l, 'la defined by their upper edges 8b, 8c in parallelism with the upper 4edges 8 and 8a and the lower edges le, iila, of the shingles proper.

The rhomboidal form of the shingles arises from the outward angular extension or flare, from the bottom edge upward, of the left hand, and laterally overlapping edges or angle-edges il, Ila of the shingles and the extension in parallelism therewith of the right hand and laterally underlapping edges I2, I2a of the extensions l', 'la and I3, Ita of the body portions.

It is to be noted that the lateral edges Il, I2, I3 and Ila, I2a, ma may be extended at any desired angularity or degree of Obliquity.

The lower or horizontal edges I0, Illa of the shingles .are commonly referred to as the weather edges. In the shingle of Figures l and 2 there is formed in the right-hand end of this weather edge a straight lock-incision I5, in substantial parallelism with the edge line I3 but inset somewhat with reference thereto, and an angular or Leshaped lock-incision It in the left-hand end of said weather edge, adjacent the lower, lefthand corner of the shingle, said lock-incision in- Ncluding an entering incision Ita in parallelism inner extremity of the entering incision lGa, to-

wards the left-hand edge of the shingle, and nally a slight down-turned incision IBc extending down from the extremity of the top incision ISb, thus providing a free tab or tongue ltd.

In shingling a roof with the shingle formed and incised as shown in Figures 1 and 2, the lower row of shingles is first laid along from left to right hand, with the left margin of each succeeding shingle overlying the right margin of the preceding one, and with the tab Id underneath the lower free margin of the extension 1, being passed into this interlocked relation through the incision I5, and iirmly anchored in place by drawing the material of the underlying right hand margin of the left hand shingle, at the extremity of the incision l5, firmly down into the shortA down-turned incision IGd. Thus each row of shingles is rmly interlocked together as laid. This row is then nailed down in conventional manner.

In laying successively the upper rows of shingles, the right hand edge I2 of each shingle is positioned adjacent the left-hand, overlapping edge Il of the shingles of the next lower row, with the upper edges 8 and 8b in substantial registry or alignment. AEach successive row of shingles is nailed down along its upper margin,

in the usual way, by nailsI (not shown). Thus a substantially close roof covering may be formed, and by pressing the lateral margins of the shingles tightly together (not here so shown), all openings may be closed against air or water. Thus the insulation is complete for retaining the heat in the house in the winter time. As the shingles are all interlocked as shown, they stand as a unit against the action of wind or rain, and single shingles cannot be loosened and dislodged. By aligning the upper edges 8 and 8b of two rows, as above suggested, a standard overlapping of the rows is eifected, and the work is also eX- pedited. However a greater or lesser degree of overlapping may be employed as desired. Also conventional lap-marks (not shown) may be made on the margins of the shingles if desired, the use of which is well known in the art. The shingles may of course be made of any desired size.

It will be noted too, that as laid, the successively overlapped lateral joints between the shingles, from the bottom row to top row, automatically fall into an alternate or stepped relation, owing to the angular extension or outward inclination of the angle-edges at the left hand.

The form of shingle shown in Figures 3 and 4 is similar to that of Figures l and 2, but in this form the interlocking incisions l5 and I6 are omitted, and the shingle is left plain. These shingles are laid similarly to the others, being nailed down along their upper and underlying margins in a conventional manner by nails (not shown).

If desired the shingles may be laid in reversed order, end for end, to the method described above, and of course with each upper row overlapping' the next lower row. This arrangement presents an attractive system or scheme of markings at the joints, but is not here illustrated.

While I have here shown and described the design and conguration of the shingles as made in accordance with my invention, same may be modified within the scope of the claims.

I claim:

1. In a roong shingle, a rhomboidal body portion for laying with its long sides extended horizontally and its lower obtuse angle to the left, a lesser, integrally formed rhomboidal extension from the body portion on the right end thereof and aligned at its lower margin with the lower margin of the body portion, the height of the lesser extension corresponding to the desired overlapping of upper rows of shingles upon lower rows, whereby by aligning the upper horizontal margins of said extensions of an upper row with the upper horizontal margins of the body portions of a lower row, the work of shingle laying may be standardized and expedited.

2. In a shingle according to claim l, there being a straight lock incision in the right end of the lower margin of the body portion, slightly inset relative to and in parallelism with the right edge line of the body portion, and a free locking tab at the lower left corner of the shingle, said tab being dened by an inverted L-shaped incision, including an entering incision of equal length and parallel with said straight lock incision, a top incision extended outward parallel with the lower edge of the shingle, and a short clown-turned incision from the end of the top incision, and whereby the right margin of one such shingle may be interlocked with the overlying left margin of a laterally aligned shingle.
